Why This Must Be Read: This fic takes two characters that I thought I was a little sick of and pitches them perfectly—both together and separately. Darcy is at her awesomest here, kicking administrative ass and outsmarting Hydra's finest at their own game, while Bruce's self-sacrificing is painfully believable—as is, for once, the relationship between them. Plus, there's Pepper and Maria pwning everyone and a nod toward everyone's favorite Avengers Tower fanon: air duct!Hawkeye.
